I have exactly this error if I build my world with CPUTYPE=p2 and
CFLAGS=-O3 in make.conf. For some reason the pthread libraries aren't
build correctly than. Probably, the optimisations make some functions
inline so they disappear in the lib or something else. I don't really
know. Building world with -O2 makes everything work.
Greetings,
Ronald.
